Can someone explain the grading system?

So today playing WW in two games, these were my grades:

I got an S- in a game where I didn't have the most kills, nor the most gold, etc. The other game I had more kills then my ENTIRE team put together and the most gold, yet I get an A+...

I don't get the grading system sometimes. In the S- game I didn't feel like I did the best, the ekko on our team carried more then I did but the A+ game I pretty much carried my entire team and turned the game around when everyone else lost their lanes.

you usually just need to add a 0 to the end of your cs for you to matter

I assume there is some sort of aggregate point total with weighted proportions going to each stat depending on how valuable Riot thinks it is for performance measurement. When that gets added up, it is compared relatively with the performances of others on that character and each grade represents a percentile range. So I'd guess S+ is 99th+ percentile, S 95-99th percentile, S- 91-95th percentile, and so on so forth.

game length affects grading quite a bit and judging from the gold of both games the A+ game went significantly longer than the S- one. KDA doesn't really reflect everything either since we have no idea how many dragons, turrets, wards you managed to help secure (and place in case of wards).

A score of 20/5/10 in a 20 min game looks much better than that same score but on a 30 min game and that one looks much better than in a 40 min game and so on and so on.

I would add what I think would help you out, but I think a much more accurate answer is:

There's a grading system. You are ranked against others using the same champ and role. Everything else is speculation. Riot won't tell us more so that people aren't just trying to game the system.

Best of luck in the future. :)

Others have mostly said what there is to be said, but it's probably important to mention that you're only compared against others playing the same champion in the same role, which notably means you are not compared to the performances of your team members.

If you have an S tier performance on a champ in a role, it won't matter if all 4 of your teammates fed to hell the whole game, or if you had a team of 4 faker clones setting game records in each of their respective other roles, as you're graded on you. (That said, it's often easier to put out a good performance when the enemy team is collectively behind, as it's easier for you to get kills/cs/objectives/etc when theres no fed enemy carries to worry about.)
